class atlas_q.stabilizer_backend.StabilizerState(n_qubits, tableau)

Bases: object

Stabilizer state represented as a tableau

A stabilizer state on n qubits is represented by a (2n+1) × 2n binary matrix: - First n rows: X part of stabilizer generators - Next n rows: Z part of stabilizer generators - Last column: phase bits (±1)

Example for |0⟩: stabilizer is Z Example for |+⟩: stabilizer is X Example for Bell |Φ+⟩: stabilizers are XX and ZZ

Methods

copy()	Create a copy of this state
init_plus(n_qubits)	Initialize |++...+⟩ state (stabilized by X on each qubit)
init_zero(n_qubits)	Initialize |00...0⟩ state (stabilized by Z on each qubit)
